Very good stuff, but there are some issues with helmets and gloves etc.
With the helmets, I noticed that the name of the textures were wrong (Helmet_19 instead of HELMET_2012). And for most of the skins, there is no texture for Helmet_2012_Glass.
I also noticed that the resolution/size of the helmets was wrong (the ratio of pixels was 2:1 instead of 4:1).
I noticed this by looking at the textures for Lewis Hamilton's skin, and comparing it to other skins.
I hope this is something that can be fixed in the future, but overall the skins are great!
